Radeon RX 6750 XT vs GeForce RTX 4090 comparison

In our benchmarks, the GeForce RTX 4090 beats the Radeon RX 6750 XT in gaming performance.

Our database shows that the GeForce RTX 4090 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the Radeon RX 6750 XT has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, the GeForce RTX 4090 has significantly more memory with 24 GiB of memory compared to 12 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 6750 XT has a significantly lower TDP at 250 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce RTX 4090 is faster than the Radeon RX 6750 XT.
